British engineering company Rolls-Royce is under fire after its faulty engine unit left a gaping hole in the left engine covering of a China Eastern flight, said a report.

Flight 736, which was heading to Shanghai from Sydney, was forced to make a return just minutes after takeoff.

“The moment that we took off the wing to my left just started making a massive amount of noise and they cleared all the seats on the left side,” one passenger told Australia's Nine Network.

Crew onboard flight 736 from from Sydney to Shanghai became aware of the damage shortly after takeoff and the pilot decided to make an emergency landing ,said a report in BBC.

All passengers were "evacuated with no injuries" and were being taken care of, an airline spokesman said.

Passengers told Australian media that they heard "a loud bang then a burning smell".

Images on social media showed a large hole on the engine.

A spokeswoman for Rolls-Royce, which manufactured the plane’s Trent 700 series engines, said in a statement: “We are aware of the incident and will be working closely with our customer and relevant partners to understand the cause of the issue.”
